Q1:10 out of 10
Q2:Yes
Q3 & Q4:"They showed up when they were supposed to, and they did their best to complete the job, even though the city didn't cooperate.

Paula F. Verified Collier Ostrom, Inc. Customer Name
Q1:10 out of 10
Q2:Yes
Q3 & Q4:"Now that I've had them in my house, they are the only contractors I would ever use. I have a big expensive house in San Francisco, and they have the keys to it. I can trust them like a family member. They took care of my animals when I wasn't there. The would make sure they didn't get out during the construction. I have never had that from any contractor. It was the personal touch from David and Everett. I felt like I was going through a family member during the whole process. It can be very disruptive using contractors, but they made it easier. "

Dan R. Verified Collier Ostrom, Inc. Customer Name
Q1:10 out of 10
Q2:Yes
Q3 & Q4:"There were really two things. One would be the overall quality of all the work, especially the small details, and second, which was especially important to my wife, was that they were so careful about the dust and debris. Unlike a lot of contractors, they were careful to seal off the negative areas where they weren't working so that the dust didn't get throughout the house. When they took down the dust sheets and vacuumed every day, it was clean and dust free. They were really good at relating personally to the customer. "

Peter M. Verified Collier Ostrom, Inc. Customer Name
Q1:10 out of 10
Q2:Yes
Q3 & Q4:"They listened to everything and made wonderful suggestions. We just happened to work really well together. They were really good, honest people. We know they will give us a fair price. They have done a lot of work for us eventhough we have had a lot of challenges, but somehow they managed to find a way. We had a mold problem that someone else was taking care of. When we came home, we found the roof was off our house. The guy who did it said, 'We'll just put some plastic over it.' In Diamond Heights, you don't just put plastic over it. We called David, and he was out here within minutes to put plywood over everything. We don't know what we would have done without him."
